G. H. SE AL COLLAR SUPPORT Filed Jan. 15, 1940 Patented Dec. 2, 1941um'reo s1 T55 earner oerce beams suPros-r George 1. Seal, Glendale,Calif I Application January 15, 1940, Serial N9.:331 3,-,9 i 2 A .3 Clims. (01. Mil-25) I This haven-tion relates to securing means for acollar support particularly adapted for use street light assemblies ofthe reflector or refractortypef 1 The general object of the invention isto pro! vide :an improved adjustable securing means tor a collar supportparticularly. adapted for use in street light head assemblies.

A more specific object of the invention is to provide improved securingmeans for attaching the reflector and/or refractor unit to the porcelainhead in a street light head assembly,

Another object of the invention is to provide a unit adapted for usewith either a reflector or a refractor unit in securing portions of astreet light in place.

Other objects and the advantages of my invention will be apparent fromthe following description taken in connection with the accompanyingdrawing, wherein:

Fig. 1 is a central sectional view of a street light head assemblyshowing my invention;

Fig. 2 is a top plan view of the collar;

Fig. 3 is a side elevation of one of my improved securing brackets;

Fig. 4 is a top plan view of the securing brackets shown in Fig. 3;

Fig. 5 is a central sectional View of a street light head assemblyshowing a modified form of my invention;

Fig, 6 is a bottom plan view of the collar shown in Fig. 5;

Fig. 7 is a side elevation of one of the modified securing bracketsshown in Fig. 5;

Fig. 8 is a top plan view of the modified securing bracket shown in Fig.7; and

Fig. 9 is a sectional view taken on line 39, Fig. 6.

Referring to the drawing by reference characters I have shown myimproved securing means as embodied in a street light head assemblyindicated generally at Ill. As shown the head assembly Ill includes acanopy ll adapted to engage a bracket (not shown).

Depending from the canopy I l is a hollow porcelain head i2 securedthereto as by screws l3 and including a depending skirt portion 14.Positioned within the head i2 is a light bulb receptacle assembly l5secured thereto as by screws 15.

The skirt i l includes radial apertures ll, each aperture being adaptedto receive one leg 28 of one of my improved securing brackets I9. Asshown in Figs. 3 and 4 each securing bracket l9 includes a body portion20 and two threaded legs l6 and 2! projecting therefrom substantially atright angles to each other. Nuts 2;; secure the screws 19 to the skirt1.4. Washers-23 arepreferably placed :beneath the units "22.

The legs 21 .of the'brackets l9 engage apertures 24% in .an upper flangeportion 25 of a refra'c'tor collar 2.6 and are secured thereto :by nuts21 with washers '28. The refractor collar- 26 includes the upper fiangeportion '25 engageable with the' skir t M, an intermediate conical skirt'pcrtion Z9 and a lower flange portion 30 recessed as at 3| on the lowerside thereof to receive a retaining ring 32. The ring 32 is removablysecured as by screw and wing-nut assemblies 33 pivoted to the flange 35as at 34 and engaging lugs 35 on the retaining ring 32.

The retaining ring 32 includes shoulders 31 adapted to engage arefractor 38. Suitable packing material 39 is disposed between theflange 25 and the skirt l4 and between the refractor 38, the flange 30and the shoulders 31 as shown.

It will be seen that the screws l9 are firmly secured to the skirtportion l4 and that the flange 25 of the collar 26 may be held in closeengagement with the skirt M by the nuts 21 thereby providing a securejoint between the porcelain head and the metallic reflector ring.

The flange 25 of the refractor collar 26 further includes apertures 40of the shape shown in Fig. 2. Through various combinations of theapertures 24 and 48 the refractor collar 26 is adapted for use withporcelain or other heads having various arrangements of apertures I!thereon.

In Fig. 5 I have shown a modified form of securing means as embodied ina somewhat different type of street light head assembly from thatpreviously described. Parts similar to those previously described aredesignated by similar primed reference characters.

Positioned within the apertures IT in the skirt I4 I provide bracketmembers 50 having threaded shank and enlarged head portions 5| thereon.As shown in Figs. '7 and 8 the head portion 5| of each bracket member 50has a threaded aperture 52 therein engageable with a screw 53. The axisof the shank of the member 50 is substantially at right angles to thescrew 53. The members 50 are inserted through apertures I1 and aresecured by washers 54 and nuts 55.

The screws 53 engage in apertures 55 in a flange 51 of a reflectorretaining collar 58. The flange 51 is engageable with the skirt l4suitable packing material 59 being disposed therebetween.

The reflector retaining collar 58 includes a skirt portion 60 from whichbosses 6| extend. The bosses Bl support threaded members 62 which engageapertures 63 in a reflector member 64 and are secured thereto by nuts 65and washers 86.

It will be seen that the collar 58 is securely held in position adjacentthe skirt I4 by my improved securing means forming a secure jointbetween the porcelain head and the metallic reflector retaining ring. Inboth types the bracket permits the ring to be drawn tightly against theporcelain so that shifting with consequent breaking of the porcelain isavoided.

From the foregoing description it will be apparent that I have inventeda novel securing means which can be economically made and which ishighly eflective for the intended use.

Having thus described my invention, I claim:

1. In a street light assembly, a canopy, a hollow vitreous headdepending therefrom, said head including a lower skirt portion, a lampbulb receptacle positioned Within said head and secured thereto, saidskirt portion including spaced radial apertures, a plurality of bracketseach including a threaded leg positioned in one of said apertures andsecured by a nut, each bracket including a second threaded leg arrangedsubstantially at right angles to the first leg, a collar having a flangeengaging said skirt portion,

said flange having spaced apertures receiving said second legs, nuts onsaid second legs and a refractor mounted in said collar.

2. In a street light head assembly, a head including a lower skirtportion, said skirt having radial apertures, a bracket including athreaded shank positioned in each of said apertures and secured by anut, each of said brackets including an enlarged head portion with athreaded aperture therein, a screw engaging said threaded aperture anddisposed substantially at right angles to said shank, a flangedreflector supporting collar having apertures, said flange engaging saidskirt and said screws passing through said flange apertures to hold thecollar in place.

3. In a street light assembly, a canopy, a hollow vitreous headdepending therefrom, said head including a lower skirt portion, a lampbulb receptacle positioned within said head and secured thereto, saidskirt portion including spaced radial apertures, a plurality offastening members each including a threaded leg positioned in one ofsaid apertures and secured by a nut, each fastening member including asecond threaded leg arranged substantially at right angles to the firstleg, a collar having a flange engaging said skirt portion, said flangehaving spaced apertures receiving said second legs.
